Aplomado Falcon Description


The Aplomado Falcon is very slender, long-winged, and long-tailed, the size of a small Peregrine Falcon
at 12–16 in (30–40 cm) long and with an average wingspan of about 36 in (90 cm), but only half the weight, at about 7.3–10.8 oz (208–305 g) in males and 9.6–16 oz (271–460 g) in females
. In adult birds, the upperparts are dark blue-grey, as is much of the head, with the usual falcon "moustache" contrasting sharply with the white throat and eyestripe.
The upper breast continues the white of the throat; there are black patches on each side of the lower breast that meet in the middle; the belly and thighs, below the black patches, are light cinnamon.
The tail is black with narrow white or grey bars and a white tip.
The cere, eye-ring, and feet are yellow or yellow-orange.
Except that females are bigger than males, the sexes are similar. Juvenile birds are very similar to adults, but their upperparts and belly band are blackish brown, the chest is streaked with black, the white on the head and breast is buffy, and the cinnamon on the underparts is paler, as are the feet.
This species may be confused with the Bat Falcon and the Orange-breasted Falcon , which have similar white-black-rust patterns below, but those species are built more like Peregrine Falcons and have solidly blackish heads and darker rufous bellies.
These two species are generally considered to belong to the same lineage as the Aplomado Falcon.
Two other Falco species of the Americas, Merlin and American Kestrel , seem to be closer to the Aplomado group than most other falcons, but the relationships of all these lineages are fairly enigmatic. All that can be said
with some certainty is that they diverged as part of an apparently largely western Holarctic radiation in the Late Miocene, probably around 8–5 million years ago.

Aplomado Falcon


The Aplomado Falcon, Falco femoralis, is a medium-sized falcon of the Americas.
The species' largest contiguous range is in South America
but not in the deep interior Amazon Basin.
It was long known as Falco fusco-coerulescens or Falco fuscocaerulescens
but these names are now believed to refer to the Bat Falcon (F. rufigularis)
. Its resemblance in shape to the hobbies accounts for its old name Orange-chested Hobby. Aplomado is an unusual Spanish word for "lead-colored", referring to the blue-grey areas of the plumage – an approximate English translation would be "leaden falcon".
Spanish names for the species include halcón aplomado and halcón fajado (roughly "banded falcon" in reference to the characteristic pattern); in Brazil it is known as falcão-de-coleira.

falcon - facts


AT RIGHTaround forty days, young Peregrines begin flying. Peregrine parents encourage flight by "baiting" the young with food, which is no longer neatly prepared and fed directly to the young. It is a lot of fun to watch young Peregrines chasing each other and everything else!
As in many other species, Peregrine young learn in part through "playing" - however, this play can be deadly serious when hunting is involved.
Peregrines hunt and eat other birds and are famed
for their speed (stooping, or diving, Peregrines
have been clocked at speeds of up to 220mph) and aerial prowess.
Here are some bird
fact sheets from one of my OTHER favorite web sites, the Animal Diversity Web

falcon Encyclopedia


AT ONE time, the type of falcon an Englishman was allowed to own marked his rank.
A king, the gyrfalcon; an earl, the peregrine; a yeoman, the goshawk; a priest, the sparrowhawk; and a servant the kestrel. Notable falconers and enthusiasts include Frederick the Second (who wrote what some consider the first book of ornithology), William Shakespeare, Marco Polo, and Ghengis Khan.

Horus in egypt history


In Egyptian mythology, the hawk, or falcon, god.
Horus is a Latin form of a Greek word for the Egyptian name Heru, or Hor.
Originally, Horus was a local god who was worshiped along
the delta region of the Nile. Eventually, his cult spread
throughout Egypt and was carried into Roman times, when he was worshiped along with his mother, Isis.
Gold Eye
The falcon, or hawk, one of the first animals worshiped in Egypt
was said to be the personification of the god Horus, who made the sky.
In predynastic times there arose several hawk deities, among the most important being the falcon god at Hierakonpolis
in Upper Egypt, where Horus took on the form of a solar disk with wings.
When the kings of the south moved into Lower Egypt, uniting the two lands, Horus became known as the Uniter of the South and North, or Upper and Lower Egypt.
He was sometimes said to be the son of the cow goddess Hathor, whose name literally means "house of Horus." Each evening he would fly into the goddess's mouth, and each morning he would emerge reborn.
In the most famous myth associated with him, however, Horus is the son of the god Osiris and the goddess Isis, and he avenges his father's murder by defeating the demonic god Set in a series of battles.
Thus Osiris is identified with the dead king and Horus with the living king. Sometimes the living king was said to embody within himself both Horus, the spirit of light, and Set, the spirit of darkness, reflecting
the eternal strife that is always present in the universe. In his role as defeater of Set,
Horus is variously portrayed as a mounted warrior with the head of a falcon and as a falcon-headed man with a large pointed spear
driven into some foe. In one version of the myth, Horus had his left eye, which signified the moon, wounded in his battle with Set, thus giving rise to one explanation for the moon's various phases.
The eye was healed by the god Thoth, and the restored eye, known as the udjat, became a powerful amulet.
Various "Horus gods" also appear in Egyptian mythology. Originally, many of them were separate deities, but eventually
they were all blended into one and were considered various aspects of the same god. Among them are Harpokrates, Harsiesis (Horus the son of Isis), Harmachis (Horus who is on the horizon), Haroeris (Horus the elder), Horus-Behdety
(Horus of Behdet), Horus Khenty en Maathyu (Horus at the head of those who see not?
also called blind Horus), Horus Khenty Khat (Horus at the head of the belly?), and Horus Netcher Nedjeitef (Horus the god, he who avenges his father).

Falcon - INSIDE THE egg


INSIDE THE egg, the Peregrine chick has its head tucked under its wing.
A large muscle called the hatching muscle runs from the middle of the neck to the top of the head. About 30 days after incubation has started, this muscle contracts.
The chick's head snaps up and the egg tooth, a hard pointed knob on top of the beak, cracks the inside of the eggshell.
This creates a "pip" - a small hole with tiny cracks spreading out across the shell. One to two days after pipping, the chick begins moving around in the shell.
The egg tooth scrapes against the eggshell, cutting a ring through it. 33 days after the egg is laid, the chick breaks out.

Falcon in history


FALCONRY IS an ancient sport.
It was practiced in China before the year 2000 BC: falconry is also the subject of some of the oldest Egyptian wall paintings.
English playwrite William Shakespeare was a falconry fan who
introduced falconry terms into popular speech: the word "Hag" or "Haggard" is the term for a mature wild hawk or falcon.
Horus, an Egyptian god, was a Peregrine falcon: the "Eye of Horus" is clearly a
stylized Peregrine falcon's eye.

PEREGRINE FALCONS


PEREGRINE FALCONS are about the size and weight of a crow - females are larger and more powerful than males.
Adults have slate dark blue-gray wings and backs barred
with black, pale undersides, white faces with a black stripe on each cheek, and large, dark eyes.
Their wings are long and pointed - Peregrines look, in a nutshell, fast.
PEREGRINE FALCONS have been called nature's finest flying machine.
They are nature's fastest fliers: Peregrines have been clocked diving, or stooping, at speeds of up to 220 miles per hour! Peregrine falcons feed primarily on birds they take in the air: their prey includes ducks, pheasants, and pigeons.
Some of the power plants that RRP works with have seen
the resident pigeon population disappear after Peregrines began nesting on site.

Falco Peregrinus


THE PEREGRINE falcon's scientific name is Falco Peregrinus, which means Falcon Wanderer. Three subspecies are recognized in North America: F.P. Pealei from the coastal islands off Alaska; F.P. Tundrius, which nests above the tree line in the Arctic; and F.P. Anatum, which once ranged over North America from coast to coast. In the 1960s, scientists discovered that DDT was interfering in the egg shell formation of meat and fish eating birds. Healthy birds were laying eggs so thin they were crushed by the weight of the incubating adult. By 1965, no Peregrine falcons were fledged in the eastern or Central United States. By 1968, the Peregrine population was completely eradicated east of the Mississippi River. In 1972, use of DDT was severely restricted in the United States and worldwide.

Falcon - EYASES ARE


EYASES ARE helpless. One parent (often the female but sometimes the male) stays
with the chicks while the other finds food for the brood.
Eyases eat an incredible amount of food - but then, they double
their weight in only six days and at three weeks will be ten times birth size.
Newly hatched chicks are wet and covered with white down.
But by three weeks of age, brownish juvenile feathers can be seen poking through the white fuzz. By five or six weeks of age, the white fuzz has been completely replaced by brown feathers.
The eyases can be observed jumping around and testing their wings, getting ready to fly. Above: This BirdCam picture of Smoke and Prescott was taken when the young falcons were about 20 days of age.

BABY FALCONS


BABY FALCONS are called eyasses.
They are covered by white down when they are born
which is replaced by feathers in three to five weeks.
Although they have a high mortality rate, Peregrines have been known
to live as long as 15 years. They usually begin breeding at about two years old.
These three young are nesting high atop a power plant stack: power
plants have the best production rates in the Midwest.

Falcon Description


Adult falcons have thin tapered wings, which enable them to fly at high speed and to change direction rapidly.
Fledgling falcons, in their first year of flying, have longer flight feathers
which makes their configuration more like that of a general-purpose bird such
as a broadwing. This is to make it easier for them to
fly while learning the exceptional skills required to be effective hunters as adults.
Peregrine Falcons have been recorded diving at speeds of 200 miles per hour (322 km/hr), making them the fastest-moving creatures on Earth.
Other falcons include the Gyrfalcon, Lanner Falcon, and the Merlin. Some small falcons with long narrow wings are called hobbies, and some which hover
while hunting are called kestrels.
The falcons are part of the family Falconidae, which also includes the caracaras, Laughing Falcon, forest falcons, and falconets.
The traditional term for a male falcon is tercel (British spelling) or tiercel (American spelling), from Latin tertius = third because of the belief that only one in three eggs hatched a male bird.[1] [2] Some sources give the etymology
as deriving from the fact that a male falcon is
approximately one third smaller than the female (Old French tiercelet).
A falcon chick, especially one reared for falconry, that is still in its downy stage is known as an eyas[3][4] (sometimes spelt eyass). The word arose by mistaken division
of Old French un niais, from Latin presumed *nidiscus ("nestling", from nidus = nest). The technique of hunting with trained captive birds of prey is known as falconry.
As is the case with many birds of prey, falcons are renowned for their exceptional powers of vision; one species has been found to have
a visual acuity of 2.6 times that of a normal human.
In February 2005, the Canadian ornithologist Louis Lefebvre announced
a method of measuring avian intelligence in terms of
their innovation in feeding habits.
The falcon and corvids scored highest on this scale.

Falcon


A falcon is any species of raptor in the genus Falco.
The word comes from their Latin name falco, related to Latin falx ("sickle")
because of the shape of these birds' wings.
